I recommend that you remove your macro and add new..this time just add the chaetomorpha.If that caulerpa goes sexual...you will not want to see the results.It will probably be too difficult to insure that all the caulerpa is gone...so it would be best to just get a new clean batch of chaeto only.Another possibility is small bits of the caulerpa could make it to your tank and get a foothold.Chaeto would be much easier to remove in this case.
